INVENTOR EA RL JUHNSON ATTORNEY Patented Dec. 15, 1953 UNITED STATES y PATENT OFFICE 2,662,503 AUTOMATIC WATERING FOUNTAIN Earl B. Johnson, Freehold, N. J. Application May 11, 1948, Serial No. 26,277 32 claims. (o1. 11s-so) This invention relates to improvements in water fountains and more particularly to drinking fountains of the type illustrated, described and claimed in my cti-pending application Serial No. 493,331 led July 3, 1943, now abandoned, and my Patent No. 2,452,305 issued October 26, 1946.

My application Serial Number 557,987 discloses a fountain having an upwardly open container having an outer peripheral edge portion, and a reservoir disposed in the container for up and down movement and providing a water space between said reservoir and container; and having a substantially peripheral margin disposable within and lower than said outer peripheral edge portion, said reservoir preventingfiow of water from the container into the reservoir except at the upper part thereof. Said reservoir is of a shape and weight to be buoyed by water in the container when less than. a predetermined small amount of water is in the reservoir, and to sink in the water when the reservoir receives a predetel-mined larger amount of water from the c0ntainer.

An upwardly pointed water supply ,iet is mounted in the lower part of the container. Water under pressure is supplied through said jet; and a yieldable sealing disc is secured to and under the aXial portion or' the reservoir and disposed over and adjacent to said jet and is adapted to rest upon the iet to stop water now therefrom when the reservoir sinks.

A cover mounted on the container is disposed over the reservoir and said space to prevent undesired material from falling into the reservoir and said space and comprising a ybowl-shaped intrannarginal part in and spaced from the reservoir, said bowl-shaped part being provided. near its bottom with an opening communicating with the reservoir.

An important object of the present invention is to provide a fountain of the general type stated above having a structure whereby a greater buoyancy is applied to the reservoir than was possible in previous structure, thereby resulting in a fountain that is more emcient in operation and which functions on a wider range of water supply pressures and provides a more uniform depth of water within the drinking area.

Another object of the invention is to provide a fountain structure whereby the same cover can be used for shallow water as required for small chicks or for deeper water for larger birds, such as grown turkeys or ducks, simply by pressing the bottom of the cover upward or downward as desired.

Another object is to provide a fountain structure whereby the operative position of the reservoir can be raised or lowered as means for raising or lowering the water level within the drinking area.

Still another object is to provide a longer lasting and more easily replaceable sealing means than the disc of the above described fountain, the disc of my previous fountain being the only part of the fountain to show wear or deterioration after comparatively long periods of use.

Another object of the invention is to provide a fountain jet structure whereby the ow of water is automatically stopped should the cover be accidentally removed or when the cover and reservoir are removed as in cleaning.

Another object of the invention is to provide a fountain structure that is more easily assembled in manufacture than heretofore, and a structure in which the component parts are easily replaceable should such parts become damaged.

The inventive features for the accomplishment of these and other objects are shown herein as embodied in a drinking fountain which brieiiy stated includes a container and reservoir so formed as to provide, as compared with my previous fountains, a relatively larger volume of water within the space between their outer and upper portions and relatively less volume of water between their lower portions.

This form has been found to provide a greater buoyancy to the reservoir than previous structure, and this greater buoyancy permits the use of a reservoir that is heavier in weight and results in a fountain that functions on a wider range of water supply pressures and also provides a more uniform depth of water within the drinking area.

The cover with its central portion is so formed that it can be used either curved upwardly for shallow water or curved downwardly when deeper water is desired.

Means are provided to make the jet replaceable and to provide it with an up and down adjustment. Adjustment of the jet slightly up o1' down correspondingly raises or lowers the operative position of the reservoir which governs the depth of water within the drinking area.

Experience has shown that raising or lowering the operative position of the reservoir as little as s12- of an inch raises or lowers the drinking area water level approximately l@ inch in a fountain i1/2 inches in diameter.

In one form of the invention a circular clip riveted to the lower portion of the reservoir and this clip provides an elongated space for a flat elongated piece oi rubber forming a sealing member. The clip has a central circular opening exposing oniy the required area of the piece of rubber approximately 2/3 of the length of the space within the clip. This provides a structure whereby the rubber can be moved along within the space when the exposed area becomes worn or damaged, the rubber is also easily removed with the point of a knife or small pointed object when it can be reversed to expose the opposite side or replaced with a new piece. This feature is very important as the area adiacent to the face of the jet must at all times be smooth and level, particularly in the smaller sized fountains.

For fountains providing greater volume of water and drinking capacity a double acting valve is provided. This valve automatically stops the low of water when the cover is removed and makes it possible to clean the fountain parts without aditional water entering the fountain during the cleaning process.

In the accompanying drawing showing by way of example several or" the many embodiments of the invention,

Fig. l shows a partial vertical axial section, partly in elevation of one form of the invention;

Fig. 2 is a bottoni plan of the mounting for sealing member;

Fig. 3 is a face view of the sealing member;

Fig. l is a View similar to Fig. l showing a modified form of the invention;

Fig. shows a fragmental vertical section, on a larger scale, of a detail of Figure 4 illustrating more clearly the double acting valve in closed operative position;

Fig. 6 shows a vertical section of a detail similar to Figure 5 (not enlarged) illustrating the double acting valve in open operative position and Fig. '7 shows a vertical section similar to Figure 6 illustrating the reservoir lifted away from contact with the double acting valve and with the valve in closed position.

ln the form of the invention shown in Figures 2 and 3 the container It! is formed with the vertical upper outer portion IQA extending dowm ward to near the water level A and curving inward toward the reservoir i l. The upper portion i GA of the reservoir i i curves relatively inwardly and downwardly from the vertical portion IGA of the container it. This provides for a relatively greater volurne of water within space l2 than within space IEA. The water within space l2 and above water level A is the only portion oi the water within the fountain that provides the buoyancy to raise the reservoir; and it has been proven by comparative testing that with a greater volume of water within space i2 relative to the volume of water within space I2A a heavier reservoir can be used which results in a fountain that will satisfactorily function on a wider range of water supply pressures than previous structures.

With previous structures, a reservoir weight oi approximately 21/2 ounces is required in a fountain i1/g inches in diameter; while with the irnproved orrn of reservoir herein a reservoir weight of approximately 3 ounces can be used in a fountain of the same diameter. This is a very important advantage in this type of fountain.

The lower portion of the reservoir II is provided with a circular clip I3 (Fig. 2) which is secured to the reservoir II by rivets I4. This Clip I3 provides an elongated space I5 for an elo-. gated rubber disc I6 (Fig. 3) which is approxi mately 2A; the length of the space I5. A circular opening i'i through the clip i3 exposes a circular area of the rubber disc i6, which can be moved along wit-hin the space i5, whereby a difierent area of the rubber disc is exposed to the circular opening I1.

The lower central portion of the container iii is provided with a downwardly extending here agonal recess I8 receiving a hexagonal flange Se. on a threaded tubular connector body I9, made from hexagonal stock. leaving the hexagonal fla-nge lSA that rests within the recess iS. A lock nut 2&3 threaded to ht the connector body i9 is screwed tightly against the outside of the container below the recess i8, thus making awater tight connection. The hexagonal recess it serves as a wrench soci-zet for holding the connector body I9 against turning when the nut 2d is tightened.

A replaceable jet 2l is threaded into the upper end of the bor 59B ci' the connector body I il and is provided with a loclr nut 2.2. The lower end of the jet 2i is pro ided with a screw driver slot 23 as a means for turning the jet for raising or lowering the operative position of the reservoir i I and for holding the jet 2l in the desired position while the lock nut 22 is being tightened. The bore ISB and the jet 2I are located off center with respect to the connector body i9. ln use when fountains are cleaned the cover 24 and reservoir II are removed, and when replaced are practically always rotated more or less from the previous position with respect to the oit-center jet 2l. Thus a different spot of the exposed area of the rubber disc I6 contacts the face of the jet 2l, each time the angular position of the reservoir i i is changed, thus changing the position of wear on the disc each time.

The cover 2t is formed with the central portion 24A curved upwardly to provide shallow water space within the drinking area for small chicks. The part 2M. may be pressed downward to the curved position shown by dotted line B to provide a dee er drinking space for large fowls. Water flows from the reservoir ii through the slot 2d into the d inlaing space.

The upper peripheral edge of the reservoir II is provided with an out-turned lip IIB loosely engageable with the vertical portion IA of the container to position the reservoir for up and down movement. This lip is bent upwardly at spaced places around the lip to provide stops IIC engageable with the cover to limit upward Inovement of the reservoir. This lip is also turned down as at IID to provide overow passages for water flowing up from the container IU over the lip into the reservoir.

The upper edge of the container i0 is provided with a cut-away iB forming a passage for air which may be trapped, under the upper part o the cover 24.

Figures 4, 5, 6 and 'I show a structure similar to Figure l but with the central portion oi the cover 2A curved downwardly to provide greater depth and volume of water Within the drinking area. This may be pressed upwardly to the curved position shown by dotted line C.

The tubular conn eter body i5 is secured to the container Iii in the same manner as in Figure 1 but instead of the jet 2! and rubber disc ES, a double acting valve is provided. The body 25 provided with a three-diameter hole 3i therethrough, the larger part of the hole starting from the lower and continuing approximately half way through where the diameter of the hole is reduced to forni a downward facing conical seat 2t. Near the upper end of the connector body 25 the hole Si is again reduced in diameter as at Si (Fig, 5) to form an upper shoulder 2li. lioosely disposed within the hole il! and extending above the upper end of the connector body 25 is a valve stem El? having an elongated enlargement 2SA and small lower extension 26B forming a lower shoulder 25C. A rubber washer 2l' provided with a central pricl: hole through which the extension 25B is forced, is forced along the extension 25B to the shoulder ZEC. An upwardly pointed 3@ is threaded into the lower end of the connector body 25, and is eneageable by the washer 2l. The oi;- erative position oi reservoir i l is raised or lowered by means oi an adjusting screw 32 threaded through the lower center of the reservoir il and provided with a lock nut 33 and a lower dat head 32 engageable with the upper end of the stem E6,

In operation the lower flat head S3 of the screw 32 normally rests upon the upper or the Valve stein pressing the rubber washer 2l upon the face of the iet till stopping flow of water when fountain is filled and reservoir i has sunk to its lowest op rative position as in Figures fl and As water is removed from within the drin space the reservoir il rises to its highest opel:` tive position as in Figure 3. In this position the water pressure has forced the rubber ,ill away from the face oi the jet liti, water lhows up wardly around the valve stern and ESA to refill the fountain. from the fountain the reservoir il rises away from the valve stern liti and the water flow the washer 2i and stem upward until the washer 2l presses against shoulder 23 as in Figure '7, stopping the flow of viator until the cover replaced forcing the reservoir li and valve stein 2G down to their operative positions as shown in Figure 6.

The improved cover with its central portion curved substantially as illustrated in either flA i,

or is one and the saine structure, and is changeable from an upwardly curved to a downwardly curved forni or vice versa by pressing the part 2M; downward or the part MB upward until oppositely curved. is easily accomplished by comparatively little pressure ci the hands.

In combination, an upwardly open container; water supply means having a water passage adapted to discharge upwardly into the lower part of the container and having an upwardly facing sealing face therearound; a sealing device engageable with said face to stop water flow; a reservoir loosely disposed within the container; structure operatively connected with the reservoir for pressing said device on said face; said reservoir having a shallow downwardly pointed lower central portion, an annular approximately horizontal intermediate part around said portion and an approximately vertical deep upper peripheral wall portion more than half as deep as the container and having a diameter several times the depth of the container; and a cover mounted on the upper edge of the container and disposed over the container comprising a bowlshaped intra-marginal part having an inwardly downwardly disposed annular side wall part having a vertical part slightly spaced from said vertical wall portion having water inlet means at the lower part, and a closed wide concave-convex central bottom portion of rm shape integrally joining the lower part of the wall part and closely spaced from said central portion and intermediate part and adapted on suiiicient pres sure to move from an upper upwardly curved position to a downwardly curved lower position and vice versa to provide a shallow or deeper drinking space.

31. In combination, an upwardly open container; water supply means having a water pasn sage adapted to discharge upwardly into the lower part of the container and having an upwardly facing sealing face therearound; a sealing device engageable with said face to stop water now; a reservoir loosely disposed within the container; structure operatively connected with the reservoir for pressing said device on said ace; said reservoir having a shallow downwardly pointed lower central portion, an annular approximately horizontal intermediate part around said portion and an approximately vertical deep upper peripheral wall portion more than half as deep as the container and having a diameter several times the depth of the container for increasing the sensitivity of movement of the reservoir to change of water level in the reservoir; and a cover on the upper edge of the container and disposed over the container and comprising a bowl-shaped intra-marginal part having an inwardly downwardly disposed annular side wall part having a vertical part closely adjacent to and slightly spaced from said vertical wall portion and having water inlet means at the lower part, and a closed wide bottom portion of rm shape joining the wall part and closely spaced from said central portion and intermediate part and adapted on suflicient pressure to be moved from an upper position to a lower position and vice versa to provide a shallow or deeper drinking space or vice versa; the close spacing of the cover to the reservoir causing said cover to coact and cooperate with said reservoir to maintain said sensitivity; and when the bottom is in said lower position to coact and cooperate with the reservoir to increase said sensitivity and when the bottom is in upper position to coact and cooperate to maintain the eniciency of the fountain when the water pressure is restored after being cut 01T.

32. A drinking fountain comprising an up wardly open supporting container having parts for holding the container upright on the ground; and a cover mounted on the upper edge of the container and disposed over the container comprising a bowl-shaped intra-marginal part having a downwardly inwardly disposed annular side wall part and a closed wide concave-convex central bottom portion of rm shape joining the lower part of the wall part and adapted on sucient pressure to move from an upper position to a lower position and Vice versa to provide a shallow or deeper drinking space.
